摘 要: | 目的:研究基质金属蛋白酶-2(MMP-2)和组织基质金属蛋白酶抑制剂-2(TIMP-2)在人肺癌组织中的表达及其与淋巴结转移和预后的关系。方法:通过免疫组织化学的方法检测42例肺癌组织中MMP-2和TIMP-2表达的情况。结果:MMP-2和TIMP-2在肺癌中表达的阳性率分别为62%和31%;MMP-2的表达与淋巴结转移呈正相关,与术后生存期的长短呈负相关,而TIMP-2的表达则相反。结论:MMP-2和TIMP-2的表达与肺癌淋巴结转移与预后密切相关,可作为判断肺癌转移和预后的指标。

Abstract: | Objective: To investigate the expression of MMP-2 and TIMP-2 inlung carcinoma and its metastasis and prognosis. Methods: SP immunohistological staining was used to detect the expression of MMP-2 and TIMP-2 in 42 cases of lung carcinoma. Results: The expression rate of MMP-2 and TIMP-2 were 62% and 31% respectively. The expression of MMP-2 was positively correlated to lymph node metastasis and negatively to survival time. The expression of TIMP-2 was negatively correlated to lymph node metastasis and positively to survival time. Conclusion: The expression of MMP-2 and TIMP-2 are closely correlated to lymph node metastasis and survival time in lung carcinoma which may serve as a parameter for determing tumor biological behavior and prognosis. |
